Study of risk perception consumption behavior of sports tourism in China

In order to further implement the "Healthy China 2030 Planning Outline" and actively develop the sports tourism industry, this study analyzed the independent variables and dependent variables that affect the urban residents’ sports tourism risk perception consumption behavior.Finally, the simultaneous regression, stepwise regression and hierarchical regression models of sports tourism risk perception consumption behavior of urban residents are constructed. The purpose is to help people effectively screen all kinds of risks in the process of sports tourism, promote the growth of sports consumption, and provide theoretical and practical guidance for the development of sports tourism


Introduction
Since the mid-1990s, with the gradual development and expansion of the global and popular sports tourism consumption market represented by fitness entertainment and leisure tourism, sports tourism has become an important part of modern people's life. Although the sports tourism market has huge potential at present and presents a momentum of rapid development, sports tourism products still occupy a small proportion in the whole tourism market. The reason is not that sports tourism products are not attractive enough, but that sports tourism products themselves contain too many risk factors. Tourists will face risks when they participate in tourism. This will directly improve the level of risk perception of sports tourism consumers, so that they will stay away from many sports tourism products and choose tourist tourism products with low relative risk coefficient. How to accurately grasp the influencing factors of people's risk perception consumption behavior in the process of sports tourism, reasonably construct the risk perception consumption behavior model of sports tourism, and understand the risk perception consumption behavior of consumers will become an important problem to be solved urgently. This study enriches sports tourism theory and risk perception theory, comprehensively grasps all kinds of risks faced by people in the process of tourism. By comparing the changes in risk perception of different groups, this study carried out corresponding market segmentation, formulated corresponding marketing strategies and optimized product design, Song and Wang, through the literature method, comparative method, carefully analysed some cities and found that the development of sports culture played an important role in promoting the development of tourism. But at the same time we also need to eliminate some negative effects. Only when we seize the opportunity to create favorable conditions to accelerate the development, improve the reputation of the city, and create a healthy sports culture tourism brand, can we enhance the competitiveness of the city [12]. González-García investigated residents' perceptions of the economic impact of sports tourism according to the population of residence, differentiating between rural, urban and coastal populations. The results of this study indicate that residents have a high regard for the impacts associated with sports tourism and that perceptions do not vary greatly, depending on the population of residence of the respondents, as well as age and sex [13]. Chang and Pei used literature method, interview method, field survey method of "big Yiyang city circle" the sports tourism development strengths, weaknesses, opportunities and threats for in-depth analysis, and put forward unified planning and dislocation development. Highlight the features, building brands; information sharing, marketing collation; to improve facilities and to attract investment and to improve the concept of service development [14]. Thus, On the basis of sports tourism, resident urban sports tourists are urban residents temporarily leave their own way of life and place to participate in or experience sports activities, nature interest, nostalgic tourism activities, leisure, entertainment, fitness, adventure activities.

Risk perception
Lawonk [15] examined the multiple dimensional aspects of perceived value in relation to purchase intention in the Eco-tourist industry. Additionally, the study evaluated the influence of trust and perceived risk as mediators on perceived value, and thus, on purchase intention. Findings showed that emotional value, functional value, boredom alleviation value, epistemic value and perceived risk are significant predictors of influenced Eco-tourism purchase intention, this study provides important implications for the study of sports tourism risk [16]. Tourism has many impacts on residents' quality of life. One outcome that can result from these impacts is the experience of stress. Individuals who experience stress are at increased risk for mental and physical illnesses. This paper examines the relationship between residents' perceived impacts of tourism on their quality of life and their experience of tourism related stress. A logistic regression model revealed that perceived risk was significantly related to the experience of tourism related stress, risks such as responsibility, knowledge, function and psychological risks may exist in the process of sports tourism. Tourism decision makers can address tourism quality of life impacts in these specific areas to help mitigate tourism related stress. Gurtner found that [17] since the turn of the century the global tourism industry has been impacted by an increasing and diverse range of external shocks. As an industry that generates hundreds of billions of dollars annually through income revenues, employment, investment and infrastructure, there has been a growing interest in trying to develop more effective management strategies to prevent and/or mitigate the adverse effects of such events, particularly at the localised region or destination level. Ritchie et al. [18] believes that there is a close relationship between tourism risk, crisis and disaster management, and future research should pay attention to the risks in tourism to improve people's willingness to travel, the interpretation of tourism risk is of great significance to this study. Williams et al. (2013) figured out that age, and tolerance of both general and tourism-specific risks, were associated with the importance of hazards as deterrents to tourist behaviour, men with lower education background are more willing to take risks than women with higher education background, conclusions on age and educational background are used in this paper [19]. Cui F et al. (2016) systematically reviewed existing researches of tourism risk perception,pointed out that there is a certain critical value for travel risk perception of tourists; Cognitive ability is an important factor affecting the level of tourists objective risk perception; and quantitative assessment of tourism risk perception level is helpful to the tourism decision making and destination management, the suggestion of cognitive ability is of reference significance to the risk perception in this study [20]. Tourist destination risk perception exerted a negative effect on tourism image, culture image, and stability image of the destination; the risk perception of tourists on tourism destinations would lead to a change in tourism attitudes, and the increased risk perception of tourists on destinations had negative effects on behavior intention (Zhang H et al.,2019) [21]. A psychometrically sound instrument-the Construction Worker Risk Perception (CoW-oRP) Scale had been developed to assess the risk perception of construction workers. CoWoRP Scale was affirmed to have three dimensions of worker risk perception, namely risk perception -probability, risk perception-severity, risk perception-worry and unsafe. These three dimensions of worker risk perception were negatively correlated with their risk-taking behavior (Man S S.et al.,2019) [22]. A reference model defining various dimensions of occupational risk perception, relevant for the different ethnicities, was identified. The authors identified 4 relevant dimensions: behavioral control, work conditions, safety climate and personal attitude (Ricci F.et al.,2019) [23]. Chaswa et al. (2020) identified six factors as variables that showed a significant effect on workers' perception of risk, include "dreaded factor","avoidability and controllability","expert knowledge","personal knowledge", "education level"and "age" [24]. Many international public-private partnership projects have suffered from frequent project pending status or failure because of dissimilar interests among stakeholders over projects' long development period, time-dependent risk, risk exposure period and risk transfer and responsibility are main risk perception gaps (Park et al., 2020) [25]. The above analysis of risk plays an important guiding significance for the relevant measurement of perceived risk in this study.
According to CoWoRP scale, combined with sport tourism, Chen Xiuping (2019) established the sports tourism consumption risk perception scale to analyze the market role and the relationship among the sports tourism, sports tourism projects and consumers, and in combination with the characteristics of the sports tourism, a kind of sports tourism consumption risk perception scale (STCRPS) that integrates the sports tourism, sports tourism project and consumers is put forward to improve the value in use of the model [26]. Chen [27] established the sports tourism consumption risk perception scale to analyze the market role and the relationship among the sports tourism, sports tourism projects and consumers in the background of the Internet era. In combination with the characteristics of the sports tourism, a kind of sports tourism consumption risk perception scale (hereinafter referred to as the STCRPS for short) that integrates the sports tourism, sports tourism project and consumers is put forward to improve the value in use of the model.Yue [28] put forward the consumption risk model of national sports tourism (referred to as CRMNST for short) based on the integration of the intelligent interactive system model (referred to as IISM for short) to optimize the decision making process of the intelligent interactive system model. The consumption risk model of tourism can be effectively integrated with the sparseness of data being processed, in particular, the offsite consumption risk of national sports tourism. Chen [29] aims to explore the relationship between risk perceptions and destination image and visit intentions with Chinese domestic tourists. He divides the destination image into cognitive and affective dimensions. The current study also examines how three risk perceptions, including physical, financial and performance risks, inuence the intention to visit a destination. Evidence from 336 Chinese domestic tourists who visited Wuhan after COVID-19pandemic suggest that perceived risk negatively and signicantly inuences cognitive and affective images. Shi [30] through the research on the perception,identification and management of sports tourism risks by means of literature material research method, analyzes the factors and characteristics that affect the perception of sports tourism risks,such as infotainment,severity,voluntary,disaster,variability, controll ability and fear,etc. Meiyang and chenguo investigate the prediction of risk events by regression analysis with dimensions of personality, risk perception and sports, relations between risk events, risk perception, and the facets of the personality dimensions via data collecting from 664 adolescent athletes aged 13-18 years (male 364, female 300) [31]. Kim examined and compared the influence of tourists€ risk perceptions on travel intentions across mega sporting event host destinations with different levels (i.e. apparent risks, less imminent risks, and unidentified risks) of such risks. The results indicated that perceived terrorism risk significantly influenced the tourists€ travel intentions [32]. Through literature review, we believe that the perceived risk of tourism includes seven risks, including economic, information, social cognition, responsibility, knowledge, function and psychological risks.

Method
According to the literature review, when people prepare to engage in sports tourism consumption, all kinds of risks including economic, information, social cognition, responsibility, knowledge, function and psychological risks naturally enter consumers' behaviors, and their purchase decisions and personality traits will affect consumers' post-purchase behaviors. In fact, purchase decision and personality are the dependent variables and independent variables of sports tourism risk perception consumption behavior, respectively. The study was verbal consent by the Ethics Committee of School of Sports, Shandong University of Finance and Economics(2021/005, May 17, 2021) and was conducted following the Declaration of Helsinki established by the World Medical Association. Submission of the online survey after completion implied consent to participate in this study, this statement has already been written at the beginning of the online questionnaire. The subjects of this study were people aged 18-60 years old who lived in urban areas of China and had fixed occupations. A total of 1000 questionnaires were distributed and 843 valid questionnaires were collected. The effective recovery rate was 84.3%.

Analysis on dependent variables of sports tourism risk perception consumption behavior
3.1.1. Dimensional identification of purchase decisions. Sports tourism risk perception included economic (factor 1), information (factor 2), social cognition (factor 3), responsibility (factor 4), knowledge (factor 5), function (factor 6) and psychological (factor 7) risks. As shown in Table 1, the analysis of explained variance shows that only one factor has eigenvalues greater than 1, and the characteristic value of the second factor starts to be less than 1. In addition, the explained variance of the first seven factors is 45.918%, indicating that the dimension of one factor can be identified. In addition, further analysis of the factor load index shows that the whole factor load (shaded part) is between 0.524 and 0.859. This indicates that the factor load of the whole questionnaire has reached the common standard, and the explanatory variables have reached 20%-50% persuasiveness.

A general analysis of purchasing decisions.
The multiple comparison method in variance analysis is used to analyze the differences in variables such as age, occupation, educational background and personal income.
Multicollinearity means that the model estimation is distorted or difficult to estimate accurately due to the existence of precise correlation or high correlation between explanatory variables in the linear regression model. Generally speaking, due to the limitation of economic data, the model is improperly designed, resulting in a general correlation between explanatory variables in the design matrix.
This study investigates the relationship between factors such as age, gender, occupation, educational background, income and personality traits and perceived risk consumption behavior, so it is necessary to use multiple comparison method to prevent the model estimation distortion or difficulty to estimate accurately due to the existence of precise correlation or high correlation between dependent variables.
(1) Analysis based on age Based on the analysis of different ages of sports tourism purchase decisions, as shown in Table 2, multiple comparison difference of Fisher's least significant difference (LSD) test showed that people under the age of < 30 years olds, 30-40 years olds, 41-50 years old and people over the age of 50, there does not appear significant difference. It shows that different age groups in sports tourism have more uniform understanding on consumer purchase decision. There is no differentiation yet.
(2) Analysis based on career The analysis of sports tourism purchase decision based on different occupations is shown in Table 3. Further multiple comparison of LSD difference test shows that the group of civil servants and posts and telecommunications, electricity, transportation; Construction, mining and manufacturing; Computer, finance and real estate; There were significant differences in the dimension of purchasing decision among the four types of occupation, education, scientific research and technical service workers (P < 0.05).
There was significant difference in the dimension of purchase decision-making between the two groups that posts and telecommunications, electric power, transportation groups and wholesale, retail, catering and leisure service workers; Computer, finance and real estate (P < 0.05).
There was significant difference in the dimension of purchase decision-making between the two groups that construction, mining and manufacturing groups and wholesale, retail, catering and leisure service workers; Computer, finance and real estate (P < 0.05).
The mean difference is significant at the 0.05 level **the mean difference is significant at the 0.01 level. https://doi.org/10.1371/journal.pone.0288735.t003 There were significant differences in purchase decision-making between computer, finance and real estate groups and education, scientific research and technical service workers (P < 0.05).
To sum up, we believe that different occupational groups have different purchasing decisions. Occupation may influence purchasing decisions.
(3) Analysis based on educational backgrounds The analysis of sports tourism consumption purchase decision based on educational backgrounds is shown in Table 4. Further multiple comparison LSD difference test shows that compared with the people of the high school and below, the people with undergraduate and graduate education is more willing to buy relevant sports tourism products, and there is a significant difference between the two, P < 0.05. Compared with the people with college and undergraduate education, the people with graduate education are more willing to buy relevant sports tourism products, and there is a significant difference between them (P < 0.05). This shows that the higher the educational level, the stronger the decision to buy sports tourism products. Educational level may have an impact on purchasing decisions.

(4) Analysis based on individual income
The analysis of sports tourism consumption purchase decision based on different individual income is shown in Table 5. Further multiple comparison LSD difference test shows that compared with the group whose individual income less than 3000 yuan, the group whose individual income above 7001 yuan shows higher purchase decision, and there is a significant difference between them (P < 0.05); Compared with the group whose individual income is between 3001-5000 yuan, the group whose individual income is more than 7001 yuan showed higher purchase decision-making, and there was a significant difference between them (P < 0.05). This shows that the higher the income level, the more willing they are to buy relevant sports tourism products and the stronger the purchase decision. Income level may have an impact on purchasing decisions.

Independent variable analysis of sports tourism risk perception and consumption behavior
3.2.1. Dimension identification of personality traits. The BFI-Fr is an effective tool to assess the five dimensions of the five-factor model of personality [33]. The psychometric qualities are excellent in several validation studies, This study adopts the research structure of the scale to classify personality traits into kindness, emotional sensitivity, experience openness, diligence and integrity and extroversion. Use the principal component analysis method to extract the factors that contribute the most to the commonality of each variable, and select the appropriate number of factors according to the extraction standard with the eigenvalue greater than 1. Then, use the maximum orthogonal rotation method to maximize the variation of each common factor in the factor load table, so as to name each group of factors and determine each dimension of personality traits. After factor rotation, there were 4 factors with eigenvalues greater than 1, and the cumulative explained variation was 62.15%. The verification results show that after factor analysis, the items of kindness personality and extroversion personality are extracted into the same factor, which is not consistent with the five personality traits to be verified in this study. [2] As shown in Table 6, select the following items according to the research needs.
Therefore, the factor selection is set as five. After orthogonal rotation, the items containing extroversion personality characteristics are independent as the fifth factor. This study verified that after factor extraction, the five factors are consistent with the five personality characteristics. In the mode fitting test, the MSA index is greater than 0.8, and the residual matrix and its partial correlation value are small, indicating that the fitting degree is good and the cumulative interpretation variance reached 67.25%. The five factors are kindness, emotional sensitivity, experience openness, diligence and integrity, extroversion.

General analysis of personality traits.
Use the multiple comparison method of analysis of variance to analyze the differences in variables such as age, career, educational background and individual income.
(1) Analysis based on age The personality traits of sports tourism consumers of different ages are statistically analyzed by Analysis of Variance (ANOVA). Levene's test for homogeneity of variance. The Levene's test is mainly used to test the homogeneity of variance between two or more samples. The samples are required to be random and independent. The test is shown in Table 7 below. The overall P values of the variances of the five personality traits are > 0.05. Accept the hypothesis of homogeneity of variance and make corresponding analysis. As shown in Table 8, further multiple comparison LSD difference test shows that there are significant differences between people aged under 30 and people aged between 30-40 in five dimensions: kindness, emotional sensitivity, Experience openness, diligence and integrity and extroversion (P < 0.05). Age may have an effect on personality traits.
(2) Analysis based on career The personality traits of sports tourism consumers of different occupations are statistically analyzed by ANOVA. The homogeneity test of ANOVA is shown in Table 9 below. Except for the dimension of diligence and integrity, the overall P values of the variances of the other four personality traits are > 0.05. Accept the hypothesis of homogeneity of variance and can be analyzed accordingly.
As shown in Table 10, further multiple comparison LSD difference test shows that organ civil servants; Culture, health and sports; Posts and telecommunications, electric power and transportation; Construction, mining and manufacturing; Wholesale and retail catering and

risk perception consumption behavior of sports tourism in China leisure service workers; Computer, finance and real estate; Education, scientific research and technical service workers, among the seven groups, there are significant differences in five dimensions of kindness, emotional sensitivity, experience openness, diligence and integrity and extroversion (P < 0.05). There were significant differences between the group of wholesale, retail, catering, leisure service workers and the group of education, scientific research and technical service workers in the four dimensions of kindness, experience openness, diligence and integrity and extroversion (P < 0.05). This shows that there are significant differences in personality traits among different occupational groups.
(3) Analysis based on educational background The personality traits of different educational backgrounds are statistically analyzed by ANOVA. The homogeneity test of ANOVA is shown in Table 11 below. The variance P values of emotional sensitivity and diligence integrity are > 0.05. Accept the hypothesis of homogeneity of variance, and conduct corresponding analysis.
As shown in Table 12, further multiple comparison LSD difference test shows that there are significant differences in the two personality trait dimensions of kindness and extroversion between high school and below educated groups and college educated groups, P < 0.05; There were also significant differences between undergraduate and graduate groups in four personality traits: kindness, openness to experience, diligence and integrity and extroversion (P < 0.05); This shows that the level of education and culture is an important variable to determine the difference of personality traits in sports tourism. It is necessary to intervene these highly educated people with personality education and personality tourism products, so as to balance their personality level.

(4) Analysis based on individual income
The personality traits of different individual incomes are statistically analyzed by ANOVA. The homogeneity test of ANOVA is shown in Table 13 below. In addition to kindness, the variance P values of emotional sensitivity, experience openness, diligence and integrity and extroversion are all > 0.05. Accept the assumption of homogeneity of variance and carry out corresponding analysis. As shown in Table 14, the further multiple comparison LSD difference test shows that between the group with an individual income of 3001-5000 yuan and the group with an individual income of more than 7001, there are significant differences in the three personality trait dimensions of experience openness, diligence and integrity and extroversion (P < 0.05); Between groups with individual income of 5001-7000 yuan and groups with individual income of more than 7001, there are significant differences in emotional sensitivity personality traits (P < 0.05). This shows that individual income is an important variable to determine the difference of personality traits in sports tourism.

Simultaneous regression model of sports tourism risk perception and consumption behavior
The simultaneous regression model integrates all explanatory variables into the regression equation to evaluate their influence on the dependent variables. [3] As shown in Table 15, firstly, determine all independent variables affecting sports tourism consumption behavior, mainly including nine variables: gender (D1), age (D2), marriage (X1), educational background (X2), family population (X3), personal income (X4), family income (X5), risk perception (X6) and personality traits (X7). Then, it can be seen that personality traits, risk perception and educational background have a high correlation with dependent variables (purchase decision-making), and reach a significant level, while other explanatory variables are relatively low. From further parameter estimation in Table 16, it can be seen from R2 = 0.310 that the overall model can explain 31% of the dependent variables. [4] If considering the simplicity of the model, the adjusted R2 is also 0.286, and the explanatory power is still relatively good, which means that these variable indicators and purchase decision variables can really explain risk perception. If we further examine the explanatory power of each explanatory variable, we can find that educational background (X2), personal income (X4) Risk perception (X6), personality traits (X7) the four variables have significant explanatory power. Among them, the beta coefficient of educational background is 0.168, t = 2.708, P = 0.007; the beta coefficient of personal income is 0.195, t = 2.75, P = 0.006; the beta coefficient of risk perception is 0.164, t = 2.265, P = 0.024; the beta coefficient of personality traits is 0.269, t = 3.632, P = 0.000. The explanatory power of other variables is not significant.
By summarizing the simultaneous regression model, it can be found that, as shown in Fig 1, each explanatory variable has different effects on the purchase decision of sports tourism consumption. [5] Among them, the effects of marriage, educational background, personal income, risk perception and personality traits on the purchase decision are 0.104, 0.163, 0.195, 0.164 and 0.269 respectively. The influence of these variables on the purchase decision of sports tourism consumption is positive, and the influence of other variables, including family population and family income, on the purchase decision is negative. Among other variables, personality traits have the highest influence, followed by personal income, risk perception and educational background. [6] In other words, the difference of personality traits has the greatest impact on consumers' choice of sports tourism consumer products. Finally, considering the characteristics of the simultaneous regression model, even the explanatory variables that didn't reach the significant level cannot be ignored, they should be included in the model, so as to obtain the final equation as follows: þ 0:170X6 þ 0:23X7 À 1:102

Stepwise regression models of sports tourism risk perception and consumption behavior
Stepwise regression models use stepwise regression analysis strategy to select predictive variables with explanatory power. The purpose of this model is to carry out predictive and exploratory research. As shown in Table 17, X7 personality trait (0.473) has the highest correlation with the dependent variable (purchase decision), which was first selected into the regression equation to form a single factor stepwise regression model 1, R2 = 0.473 224, the single factor of personality can explain 22.4% of people's decision-making process of sports tourism consumption. [7] Then, educational background as the second factor, because the partial correlation coefficient between it and its dependent variable is high, and the predictive power reaches the significant level of 0.05, it is selected as the second variable in the model to form a two-factor stepwise regression model 2, R2 = 0.05252, personality traits and educational background can explain 25.2% of people's decision-making process of sports tourism consumption. [7] Then, according to this, the explanatory variables of personal income, family population and risk perception enter the regression equation, and gradually form a three factor, four factor and five factor stepwise regression model of sports tourism consumption behavior, with R2 of 0.5, respectively, 265, 0.283 and 0.296, the final five factor model can explain 29.6% of people's decision-making process of sports tourism consumption [8].
Further analysis shows that, as shown in Figs 2-6, with the entry of other explanatory variables, the influence of personality traits on sports tourism consumption behavior (purchase decision) decreased from 0.473 to 0.287. [9] Similarly, the influence of educational background on sports tourism consumption behavior (purchase decision) also decreased from 0.187 to

PLOS ONE
risk perception consumption behavior of sports tourism in China 0.146. Only the influence of personal income variables on sports tourism consumption behavior (purchase decision) increased from 0.116 to 0.222, which shows that the explanatory variables affect each other, have a covariant linear relationship, and jointly affect the occurrence process of sports tourism consumption behavior (purchase decision) [10].
Finally, from the best stepwise regression model of sports tourism risk perception in Fig 6, it can be seen that, the influences of explanatory variables on sports tourism consumption behavior (purchase decision) are varies. [11] The most influential factor is still personality traits, with an influence coefficient of 0.287, followed by personal income, family income, risk perception and educational background, with their influence coefficients of 0.222, -0.164, 0.160 and 0.146 respectively. Among them, the influence of family income on purchase decision is negative, which is different from the daily reality to some extent, further logical analysis is required. Other explanatory variables have reasonable explanations. [12] With the increase

Hierarchical regression model of sports tourism risk perception and consumption behavior
As shown in Table 18, The demographic variables have significant explanatory power for the dependent variable, sports tourism consumption behavior (purchase decision), R2 = 0.190, f = 9.042, P < 0.01. This shows that the demographic variable group can explain 19.0% of the variation of the dependent variable, among which the explanatory power of educational background is the strongest, (beta) reaches 0.335, and there is a significant difference, P < 0.01,

PLOS ONE
risk perception consumption behavior of sports tourism in China followed by marriage, (beta) reached 0.218, but there was no significant difference (P > 0.05), followed by age and personal income, which reached 0.144 and 0.141 respectively, and the two variables reached significant differences (P < 0.05) [13].
After the risk perception variables of the second block were put into the model, the explanatory power for the dependent variables reached, R2 = 0.276, f = 12.783, P < 0.01. The interpretation increment Δ R2 is 0.0186, Δ f = 31.735, Δ P = 0.000 < 0.01, which shows that the investment of risk perception block can effectively improve the explanatory power of the model. [14] In other words, the increment of blocks is statistically significant, after controlling the influence of demographic variables, risk perception variables can contribute an additional 8% explanatory power. The explanatory power contributed by risk perception variables (beta) reached 0.339, t = 5.633, P < 0.01.
It is worth noting that the explanatory power of some demographic variables in the first block shows a downward trend, in which the changes of "marriage", "educational background" and "family population" are the most obvious, which shows that among the demographic variables controlled, the risk perception variables have a better explanatory power for purchase decision-making [15].
In the third stage, the explanatory power increment of the newly added personality trait block for the dependent variable is Δ R2, 0.034, Δ f = 13.193, Δ P = 0.000 < 0.01, which has statistical significance, which shows that the input of personality trait area group can effectively improve the explanatory power of the model, making the explanatory power of all models reach 0.310, f = 13.345, P < 0.01. Moreover, further observation of other explanatory variables shows that the beta of the explanatory variable of personality traits has decreased from 0.339 to 0.170, which shows that personality traits have a certain impact on the explanatory variables of risk perception, and there is a collinear relationship between them. After all, both explanatory variables belong to the psychological characteristics of consumers and have interactive effects [16].
According to the construction and analysis of the three blocks, we can establish three groups of different regression equations, which represents the regression model under different combinations of independent variables. After the last block enters the equation, all independent variables are included in the regression equation. At this time, the result is completely equivalent to the simultaneous regression model. Therefore, simultaneous regression is a special case of hierarchical regression model.

Discussion
The results show that, compared with women, men are more willing to buy relevant sports tourism products again, while women's willingness to buy is relatively lower, this verifies Williams et al.(2013)'s finding, so we should mobilize the initiative of female. Culture, health and sports, government civil servants, wholesale and retail catering and leisure services, compared with the three occupational groups, construction, mining and manufacturing workers, posts and telecommunications, electric power, transportation, education, scientific research and technical services workers, computers, finance and real estate workers are more willing to buy sports tourism products, there were significant differences among some occupational groups, this is consistent with Gurtner(2014)'s findings, occupation had a certain impact on tourists' risk perception. Compared with people with high school and below, people with undergraduate and graduate education are more willing to buy relevant sports tourism products, and there are significant differences between them. It indicates that education background level would affect the risk perception of sports tourism, which support Rojo(2020)'s findings in sociodemographic characteristics of tourists. Consumers' personality traits show significant differences in age, individual income, career and educational background, personality traits play an important role in risk perception of consumers, this further supporting the views of Cui The simultaneous regression model of sports tourism risk perception consumption behavior shows that the four variables of educational background (X2), personal income (X4), risk perception (X6) and personality traits (X7) have significant explanatory power, and the model explanation R2 = 0.310; the stepwise regression model of sports tourism risk perception consumption behavior shows that based on educational background (X2), individual income (X4), risk perception (X6), personality traits (X7) and family population (X3), the five factors model has significant explanatory power, and the model explanation R2 = 0.296; through the establishment of the hierarchical regression model of consumption behavior of sports tourism risk perception, it shows that based on educational background (X2), personal income (X4) Risk perception (X6), personality traits (X7), the four variables have significant explanatory power. The model explanation R2 = 0.310, which is the same as the sports tourism risk perception consumption behavior simultaneous regression model, but shows the variables that cannot be explained by the simultaneous regression model, that is, it further highlights the important role of risk perception and personality in sports tourism consumption behavior, this confirms the results of Scott & Steiger (2013) and Anuar & Sulaiman (2017) that risk perception has a direct impact on tourists' decision to travel or not.

Research limitations and suggestions
The application of risk perception in sports tourism belongs to a relatively new field, and this study is at most a preliminary exploratory study. After all, this research involves a lot of theoretical knowledge in psychology, as well as relevant theoretical knowledge in the field of economics, which is obviously cross-disciplinary and difficult. In addition, a certain amount of practical experience is needed to gain profound perceptual experience. Subsequent research will increase the accumulation of practical perceptual experience, especially supplement or revise some items through participatory survey, so as to further improve the scale. According to the research results, the following suggestions are put forward: 1. Fully expand a variety of publicity channels, further increase the publicity of sports tourism, improve people's understanding of sports tourism. At present, it is difficult to make people deeply understand the functional value of sports tourism products by simply using traditional publicity channels such as news reports and TV advertisements. Today's people need to experience before they buy, and are fully integrated into the experiential economy.
